Class MutableClassToInstanceMap<B>

    • Method Detail

      • create

        public static <B> MutableClassToInstanceMap<B> create()
        Returns a new MutableClassToInstanceMap instance backed by a HashMap using the default initial capacity and load factor.
      • create

        public static <B> MutableClassToInstanceMap<B> create​(java.util.Map<java.lang.Class<? extends B>,​B> backingMap)
        Returns a new MutableClassToInstanceMap instance backed by a given empty backingMap. The caller surrenders control of the backing map, and thus should not allow any direct references to it to remain accessible.
      • delegate

        protected java.util.Map<java.lang.Class<? extends B>,​Bdelegate()
        Description copied from class: ForwardingObject
        Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
        Specified by:
        delegate in class ForwardingMap<java.lang.Class<? extends B>,​B>
      • entrySet

        public java.util.Set<java.util.Map.Entry<java.lang.Class<? extends B>,​B>> entrySet()
        Specified by:
        entrySet in interface java.util.Map<java.lang.Class<? extends B>,​B>
        entrySet in class ForwardingMap<java.lang.Class<? extends B>,​B>
      • putAll

        public void putAll​(java.util.Map<? extends java.lang.Class<? extends B>,​? extends B> map)
        Specified by:
        putAll in interface java.util.Map<java.lang.Class<? extends B>,​B>
        putAll in class ForwardingMap<java.lang.Class<? extends B>,​B>
      • putInstance

        public <T extends B> T putInstance​(java.lang.Class<T> type,
                                           T value)
        Description copied from interface: ClassToInstanceMap
        Maps the specified class to the specified value. Does not associate this value with any of the class's supertypes.
        Specified by:
        putInstance in interface ClassToInstanceMap<B>
        the value previously associated with this class (possibly null), or null if there was no previous entry.
      • getInstance

        public <T extends B> T getInstance​(java.lang.Class<T> type)
        Description copied from interface: ClassToInstanceMap
        Returns the value the specified class is mapped to, or null if no entry for this class is present. This will only return a value that was bound to this specific class, not a value that may have been bound to a subtype.
        Specified by:
        getInstance in interface ClassToInstanceMap<B>
